Abstract This design is a hotel HVAC system design in Zhenjiang。 The central air conditioning system is designed for a 15 storey hotel。
The main contents of the design include: through the understanding of the details of the building, the building of the room to carry out preliminary design calculations。 The design criteria and design scheme of each room in the hotel are determined by the result of the budget estimate。 Then search for the local design parameters and design standards in Zhenjiang, through consultation, discussion and analysis, comprehensive development level and construction quality and other factors。 choosing the most appropriate design
The design of the central air conditioning system began from Hongye computational load start, reasonable comprehensive system, selection of appropriate energy loss factor, and carries on the analysis of each hotel room, through the application of Hongye software that more reasonable load。
Based on the understanding of the basic situation of the hotel, the comprehensive design parameters and load, the system program selection。 With a return air system and fan coil plus fresh air system independent whole building。 Fan coil unit plus fresh air system in the fresh air treatment to the indoor state point of the first, and then directly to the indoor, indoor load is not assumed。 In the design of water system, by reference to other
engineering examples, combined with the actual situation of the building, the use of different way closed system。 The expansion tank should be set at the top of the hotel。 。
After determining the scheme, the resistance calculation of the air system and water system is carried out, and the path of the pipe and the pipe line is determined, and the most unfavorable path resistance is obtained。 And refer to the cooling load and air supply air flow, etc。 to select the corresponding end of the air conditioning and auxiliary equipment。 And CAD is used to draw the relevant diagram。
